C# ComboBox extension

[thesadguy]

Hi all...

I'm still busy with my foray into C#.

I'd like to be able to extend a System.Windows.Forms.ComboBox to customise the way it looks. Can anyone please give me some guidance as to how to do the following:

1) Can I make the text-portion of the ComboBox invisible? So that only the dropdown arrow is visible. Then clicking on the dropdown arrow makes the list drop down (seemingly out of nowhere).
2) Can I customise what the dropdown arrow looks like? The standard arrow is too plain, and I'd like to create a sleeker look

The OnPaint method will need to be re-written/modified. I can't remember the name, but you get software that opens up the standard methods for controls. I'll get back to you on that one.

I had to do that with MenuItems once in 2003, to get a "menu icon" displayed next to the text... Was fun.

Found the answer to the first question here:

Have you learned about UserControls yet?

Sounds like what you are trying to do would best be done by creating a usercontrol that inherited from ComboBox

Good suggestion.
